With the looming inauguration, the FBI is warning all 50 states of credible threats of protests at state capitals. The riot at the Capitol in Washington, DC resulted in five deaths including a Capitol Police officer and a woman shot inside the Capitol Building. There were also more than 70 arrests due to the protests. Despite warnings about demonstrators, the Capitol Police did not beef up their staffing and were grossly unprepared for the escalation that ensued.
